Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Low methane emissions from nutrient‐rich former river channels in a hydrologically managed dryland delta

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Anthropogenic stresses in dryland regions can alter hydrology, salinization, and biogeochemical processes. How these pressures influence methane (CH4) cycling and emissions from aquatic ecosystems remains poorly understood. Over the course of 1 year, we measured diffusive and ebullitive CH4 emissions from resacas—shallow, hydrologically ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

open access: yesOikos, Volume 2026, Issue 5, May 2026.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.
